It might mean there is an intermittent connection or cold solder joint somewhere inside the set.
But I wouldn't just settle on that.
Here are some other things to check:
1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?
Here is what I suggest:

ONE: Give it a hard reset. Possibly the software codes in the power management are corrupted. Just unplug the tv line cord for 4 hours. That will reset everything internally to factory defaults.

TWO: Give it the old whacking test. Just bang on the cabinet in many places with your hand or fist. That will restart any cold solder joints or loose connections.

THREE: If the above procedure does not help, then you will have to call in an expert tv tech; OR just live with it and put in a line cord switch so that when it is OFF, it is really OFF.

i believe your tv is getting overheated, possibly from dust getting onto the electronic components inside. or the inverter board for the lcd panel inside is going bad, alot of times it is the capacitors on the lcd inverter board going bad.

Please pack the Sharp back into your car & get the money back. One thing I love about this website is how folks will talk about the historic/chronic problems of things. Don't even worry about fixing it. Run, don't walk, back to where you purchased it. Next, consult a "Consumer's Report" type of ezine & find a better model!!
